The deformation resistance of Fe–Mn–V–N alloy under different deformation conditions was investigated by hot compression method on thermal simulator. Effects of deformation degree, deformation temperature, and strain rate on deformation resistance were analyzed. The results show that when other conditions are constant, the deformation resistance increases with the increase in deformation degree and...
With the increase of the capacity of photovoltaic (PV) systems, how to alleviate the problem caused by the random output power of PV system becomes significant. This paper uses Markov model to correct prediction results of power generation for grid-connected PV system based on gray neural network model. Using the hourly data of PV system output power under similar climate conditions, gray model of...
This paper develops and access the implications of the exogenous growth model of Stokey(1998) for the augment endogenous time preference and the effect of public finance on pollution. The model predicts that tax can change consumers' time preference, then it also affect pollution stock. The model implies that in the poor economy taxing on consumption will decrease the capital stock and may do harm...
Designed an automatic temperature control (ATC) system to arise the stability of laser diode (LD). Established a mathematical model of thermoelectric cooler (TEC) based on the peltier cooling principle. Simulated ATC by MATLAB and analyzed on the simulation results. Designed ATC circuit driver of the TEC of LD. Obtain high speed and high precision ATC system in the room temperature environment. Its...
In this paper, the author has discussed the optimum industrial cooperation problem in the background of multilateral regional cooperation. The problem of the optimum industrial cooperation has been converted into a mixed-integer linear programming model by the author who has synthesized the influence of the following factors: the connection between the cooperation industry and other industry, the...
The study of knowledge is an important part of knowledge management. In this paper, the mathematical model of knowledge field has been built up in the way of vector field, and the Laplace's equation of knowledge potential has also been built up. This paper takes those examples to explore the solution of mathematical model of knowledge field. It figures out the rules of diffusion of knowledge under...
In this paper, the knowledge potential of knowledge field has been studied in the way of vector field, the Laplace's equation of knowledge potential has been built up, the establishment of mathematical model of knowledge potential has been explored, and the solution of mathematical model of knowledge potential is in the way of variables separation. It aimed at providing a way of quantitative analysis...
Current active transit signal priority (TSP) methods are based on real-time detection of information, often with the green extension and early green to make bus pass through the intersection as soon as possible. In this paper, according to domestic environment, applying active transit signal priority in artery coordination system, using related transit priority principle and parameter, can not only...
Bilateral control of teleoperation is one of the typical methods for half-automatic control of space robotic system. This paper focuses on the task requirement that the space robot monitoring in orbit (no contact with environment), introduces a half closed-loop framework to construct the bilateral control system with force feedback. First, dynamic model was built, and then after the Lyapunov stability...
Gun's vibration during its shooting makes projectile impact bore much more fiercely, which cause projectile's initial disturbance and affect gun's firing accuracy. Among gun's multiform vibrations, lateral vibration has the maximal influence to firing accuracy. The paper builds simulation model of gun barrel's lateral vibration based on finite element method and ascertain the equations of gun barrel's...
Based on the review of the relevant researches in the field of investor relationship management, this research analyzed the relationship between investor relationship management and investment satisfaction, developed a theoretical model, and made an empirical test. A sample of 241 investors of listed companies was used to test the model we presented. The result indicates that investor relationship...
As the second largest in the world, the Chinese automobile market has become more and more important for automakers. However, the competition pressure in this market is ever increasing. To keep profitable, the automobile companies must pay special attention to cost control. Since the procurement cost takes most part of the complete vehicle cost, reducing procurement cost was made the first choice...
Considering the limitation and deficiencies in traditional safety monitoring of hoisting equipment which adopts the load moment limiter to monitor safety, a scheme of the stability monitoring for the large-scale hoisting transfer equipment is put forth. The method of measuring hydraulic leg forces by weighing sensor to judge safety for the hoisting equipment is adopted in this scheme. By analyzing...
